0445110196diesel Injector Nozzle 0986435057 Oil Sprayer A668070128 for Mercedes Benz

<Product Description>
This precision-engineered assembly is an electronically controlled high-pressure common-rail diesel fuel injector (Part ID: 0445110196 / 0 445 110 196; common OE cross-references include 0445110195, 0986435092, A6460700987, 6460700987, A646070098780, etc.). It is designed primarily for the OM646/OM647 series 2.2 CDI diesel engine platform and is widely used in models such as the C-Class (200/220 CDI), E-Class (200/220 CDI), Sprinter, Vito, and Viano. As a core component of the fuel supply system responsible for controlling diesel atomization quality and injection timing, it precisely meters high-pressure diesel and rapidly disperses it into ultra-fine particles in response to millisecond-level electrical signals, thereby promoting thorough mixing and combustion with the intake air.

The component is manufactured to standards emphasizing high-precision tolerances and rapid, millisecond-level response times. The core control valve spool and needle valve assembly are crafted from aerospace-grade, hardened special alloy steel, featuring ultra-precise geometric grinding and low-friction polishing. The surface is finished with a dense, ultra-hard coating that effectively prevents internal scratching and pressure loss caused by fuel impurities. Upon installation, drivers and technicians will notice immediate improvements: crisp, reliable cold starts and quiet, vibration-free idling. Whether climbing steep hills, navigating stop-and-go traffic, or cruising long distances, the throttle response is sharp and agile, and acceleration is robust yet smooth. Additionally, the unit reduces black smoke emissions, delivering satisfactory fuel efficiency and a refined driving experience. </Product Description>

<Product Advantages>
**Standardized Smart Manufacturing and Quality Control from the Source Factory.** We effectively reduce procurement costs by eliminating issues common to intermediary distribution—such as excessive component tolerances, uneven fuel delivery across cylinders, and high-pressure leakage risks. Leveraging a standardized production base, we implement end-to-end quality control and remove unnecessary markups. This ensures highly consistent fuel injection pressure and flow rates across all cylinders, providing reliable power for vehicle and equipment operations while cutting maintenance budgets.

**Rigorous Testing on Ultra-High-Pressure Digital Dynamic Test Benches.** We address the common pitfalls of low-quality replacements—such as response lag, pressure-release sticking (causing engine misfires and vibration), and wasted labor/costs from repeated installation and adjustment. Every injection assembly undergoes automated testing before leaving the factory; flow rates and sealing integrity are precisely calibrated across various pressure ranges in simulated high-temperature, ultra-high-pressure environments. This ensures "ready-to-install" performance, drastically saving time and costs associated with equipment installation and tuning.

**Large-Scale Warehousing and Rapid Shipping Response.** Recognizing that daily commuter and commercial transport vehicles are high-utilization productivity tools, we aim to prevent the costly losses incurred when fuel system failures cause vehicle downtime. Our warehouse maintains ample stock year-round; orders are packed and shipped within 24–48 hours of confirmation. This significantly shortens logistics wait times, helping fleets and owners quickly resume operations and avoid losses due to downtime.

**Special Quenched Alloy Needle Valves and Wear-Resistant Hardened Coatings.** We tackle issues where poor diesel lubricity or high sulfur/impurity content leads to premature wear of precision mating parts and valve core seizing. Our core components utilize high-hardness special bearing steel and anti-corrosion surface treatments, offering superior fatigue and wear resistance. They maintain stable performance even under harsh conditions and prolonged high-load operation, reducing the extra expenses associated with frequent repairs. </Product Advantages>

<Application Scenarios>
High-quality diesel passenger vehicles in urban commuting and highway cruising scenarios: Diesel sedans and crossovers frequently start and stop in urban traffic, placing high demands on fuel delivery response speed and idle stability. Maintenance personnel should replace the unit with this high-precision common rail injector when owners notice significant idle vibration, sluggish acceleration during overtaking, or excessive exhaust smoke. After installation, the fuel injection response is sharp and immediate; the engine returns to a quiet, smooth idle, and power is delivered steadily with just a light touch of the accelerator.

Light-duty passenger/cargo transport and intercity business/logistics delivery scenarios: Business MPVs and small logistics vans frequently operate on intercity delivery routes, often cruising under high loads for extended periods. When vehicles experience sluggishness on hills in high gears, abnormal fuel consumption, or engine misfires, the maintenance team installs a full set of high-specification fuel injectors. Precise control over atomization and flow restores the engine's robust power, significantly improves fuel efficiency (km/L), and ensures timely deliveries.

Q: Can the product be used immediately after installation, or is it necessary to input a correction code?
A: Each fuel injector is assigned a unique flow correction code (IMA/QR code) during factory testing. We recommend using a diagnostic tool to program this code into the engine control unit (ECU) after installation to achieve optimal fuel efficiency and smooth operation.

Q: What are the stock levels and lead times for bulk orders?
A: We operate our own factory and large-scale warehouses, maintaining substantial, year-round stock of this model. Standard orders are packed and shipped within 24–48 hours, while bulk orders can be quickly scheduled for production.

Q: How are product quality and performance ensured before leaving the factory?
A: All fuel injectors undergo assembly in a Class 100 cleanroom environment and 100% bench testing across all operating conditions. Tests cover critical metrics such as sealing integrity, pre-injection volume, full-load injection volume, and fuel return volume; our rigorous standards ensure that every unit shipped is a high-quality product.

Q: What is the warranty period, and how is after-sales support handled?
A: We offer a 12-month warranty. Should a performance failure occur due to non-human factors within the warranty period, we provide rapid replacement or technical support to ensure a worry-free experience.
